Vacuum skin package having implosion-resistant top web

BACKGROUND

0001Vacuum skin packaging (VSP) is carried out by placing a product on a support member, placing the support member with product thereon into a vacuum chamber in which the atmosphere is evacuated and a top web is drawn upward against a heated dome and thereafter draped down over the article and support member. The top web is made from a thermoplastic material.

0002After the top web is draped over the released, with the resulting atmospheric pressure forcing the top web to conform to the shape of the product and to that portion of the upper surface of the support member which extends around the product and is not covered by the product. As a result, the top web conforms precisely to the product and the surrounding portion of the upper surface of the support member, and together with the support member, forms a vacuum skin package which surrounds the product. When the vacuum is released from the chamber and atmospheric pressure comes to bear on the top web, the top web is thermoformed to take (i) the shape of the exposed extending portion of the support member, as well as (ii) the shape of the exposed surface of the product.

SUMMARY

0003Depending upon the nature of the product and the shape of the support member, the atmosphere can cause portions of the heated top web to be stretched to a high degree. It has been found that for some products, and with some support members, the top web can be drawn so much that it “implodes,” i.e., fractures in a manner that forms one or more holes in the top web.

0004Various food products which can cause the top web to implode include, for example, a plurality of bone-in pork chops in a shingled arrangement on the top of the support member. Another embodiment that can cause top web implosion is two products placed flat down on the support member without touching one another but with a small gap therebetween. Yet another embodiment is a plurality of pork chops in overlapping relationship with an unfilled volume beneath (commonly referred to as an “undercut”) at least a portion of one of the chops, with the top web being so drawn into the unfilled volume by the returning atmosphere that the top web fractures during the final stage of forming the vacuum skin package. In has been found that bone-in meat products produce a greater implosion challenge than boneless meat products.

0005Another factor which can enhance the risk of top web implosion is a support member in the form of a tray having side walls extending upward from a product support surface. During the formation of the vacuum skin package, the top web is drawn more in order to cover the exposed surfaces of the side walls as well as any exposed surface of the product support surface.

0006A first aspect is directed to a packaged product comprising a product and a vacuum skin package surrounding the product. The vacuum skin package comprises a support member having an upper surface, and an implosion-resistant thermoplastic top web. In the package, the top web conforms to both (i) an upper surface of the product, and (ii) a portion of the upper surface of the support member, the portion being uncovered by the product. The thermoplastic top web comprises a member selected from the group consisting of: (iii) at least one ethylene/α-olefin copolymer in a total amount of from 55 wt % to 85 wt %, based on total weight of the top web, and (iv) a blend of ethylene/α-olefin copolymer and cyclic olefin copolymer, the ethylene/α-olefin being present in the top web in a total amount of from 30 wt % to 80 wt %, and the cyclic olefin copolymer being present in the top web in a total amount of from about 1 wt % to 50 wt %, based on total weight of the top web.

DETAILED DESCRIPTION

0017As used herein, the term “film” is used in a generic sense to include plastic web, regardless of whether it is film or sheet.

0018As used herein, the term “packaged product” refers to a product packaged in a packaging article.

0019As used herein, the term “packaging article” refers to an article made from packaging materials, the article surrounding a product or being designed to surround a product.

0020As used herein, the phrases “seal layer”, “sealing layer”, “heat seal layer”, and “sealant layer”, refer to an outer film layer, or layers, involved in the sealing of the film to itself, another film layer of the same or another film, and/or another article which is not a film. The phrase “sealant layer” generally refers to the inside film layer of a package, the inside layer frequently also serving as a food contact layer in the packaging of foods.

0021As used herein, the term “seal” refers to any seal of a first region of a film surface to a second region of a film surface, wherein the seal is formed by heating the regions to at least their respective seal initiation temperatures. The heating can be performed by any one or more of a wide variety of manners, such as using a hot wire, hot knife, heated bar, hot air, infrared radiation, ultrasonic sealing, etc. More preferably, the seal is formed by hot wire and/or hot knife. As is known to those of skill in the art, a static lap seal is another seal useful in forming a package from the film of the present invention.

0022As used herein, the term “polymer” refers to the product of a polymerization reaction, and is inclusive of homopolymers, copolymers, terpolymers, etc. In general, the layers of a film can consist essentially of a single polymer, or can have still additional polymers together therewith, i.e., blended therewith.

0023As used herein, the term “copolymer” refers to polymers formed by the polymerization reaction of at least two different monomers. For example, the term “copolymer” includes the copolymerization reaction product of ethylene and an alpha-olefin, such as 1-hexene. However, the term “copolymer” is also inclusive of, for example, the copolymerization of a mixture of ethylene, propylene, 1-hexene, and 1-octene.

0024As used herein, a copolymer identified in terms of a plurality of monomers, e.g., “propylene/ethylene copolymer”, refers to a copolymer in which either monomer may copolymerize in a higher weight or molar percent than the other monomer or monomers. However, the first listed monomer preferably polymerizes in a higher weight percent than the second listed monomer, and, for copolymers which are terpolymers, quadripolymers, etc., preferably the first monomer copolymerizes in a higher weight percent than the second monomer, and preferably the second monomer copolymerizes in a higher weight percent than the third monomer, etc.

0025As used herein, copolymers are identified, i.e., named, in terms of the monomers from which the copolymers are produced. For example, the phrase “propylene/ethylene copolymer” refers to a copolymer produced by the copolymerization of both propylene and ethylene, with or without additional comonomer(s).

0026As used herein, terminology employing a “/” with respect to the chemical identity of a copolymer (e.g., “an ethylene/alpha-olefin copolymer”), identifies the comonomers which are copolymerized to produce the copolymer. As used herein, “ethylene alpha-olefin copolymer” is the equivalent of “ethylene/alpha-olefin copolymer.”

0027As used herein, the phrase “heterogeneous polymer” refers to polymerization reaction products of relatively wide variation in molecular weight and relatively wide variation in composition distribution, i.e., typical polymers prepared, for example, using conventional Ziegler-Natta catalysts. Heterogeneous polymers are useful in various layers of the film used in the present invention. Although there are a few exceptions (such as TAFMER®) linear homogeneous ethylene/alpha-olefin copolymers produced by Mitsui Petrochemical Corporation, using Ziegler-Natta catalysts), heterogeneous polymers typically contain a relatively wide variety of chain lengths and comonomer percentages.

0028As used herein, the phrase “homogeneous polymer” refers to polymerization reaction products of relatively narrow molecular weight distribution and relatively narrow composition distribution. Homogeneous polymers are useful in various layers of the multilayer film used in the present invention. Homogeneous polymers are structurally different from heterogeneous polymers, in that homogeneous polymers exhibit a relatively even sequencing of comonomers within a chain, a mirroring of sequence distribution in all chains, and a similarity of length of all chains, i.e., a narrower molecular weight distribution. Furthermore, homogeneous polymers are typically prepared using metallocene, or other single-site type catalysis, rather than using Ziegler Natta catalysts.

0029More particularly, homogeneous ethylene/alpha-olefin copolymers may be characterized by one or more methods known to those of skill in the art, such as molecular weight distribution (M_w/M_n), composition distribution breadth index (CDBI), and narrow melting point range and single melt point behavior. The molecular weight distribution (M_w/M_n), also known as polydispersity, may be determined by gel permeation chromatography. The homogeneous ethylene/alpha-olefin copolymers useful in this invention generally has (M_w/M_n) of less than 2.7; preferably from about 1.9 to 2.5; more preferably, from about 1.9 to 2.3. The composition distribution breadth index (CDBI) of such homogeneous ethylene/alpha-olefin copolymers will generally be greater than about 70 percent. The CDBI is defined as the weight percent of the copolymer molecules having a comonomer content within 50 percent (i.e., plus or minus 50%) of the median total molar comonomer content. The CDBI of linear polyethylene, which does not contain a comonomer, is defined to be 100%. The Composition Distribution Breadth Index (CDBI) is determined via the technique of Temperature Rising Elution Fractionation (TREF). CDBI determination clearly distinguishes the homogeneous copolymers used in the present invention (narrow composition distribution as assessed by CDBI values generally above 70%) from heterogeneous polymers such as VLDPE's which are available commercially which generally have a broad composition distribution as assessed by CDBI values generally less than 55%. The CDBI of a copolymer is readily calculated from data obtained from techniques known in the art, such as, for example, TREF as described, for example, in Wild et. al., <i>J. Poly. Sci. Poly. Phys. Ed</i>., Vol. 20, p.441 (1982). Preferably, the homogeneous ethylene/alpha-olefin copolymers have a CDBI greater than about 70%, i.e., a CDBI of from about 70% to 99%. Such homogeneous polymers exhibit a relatively narrow melting point range, in comparison with “heterogeneous copolymers”, i.e., polymers having a CDBI of less than 55%. Preferably, the homogeneous ethylene/alpha-olefin copolymers exhibit an essentially singular melting point characteristic, with a peak melting point (T_m), as determined by Differential Scanning Colorimetry (DSC), of from about 60° C. to 105° C. Preferably the homogeneous copolymer has a DSC peak T_mof from about 80° C. to 100° C. As used herein, the phrase “essentially single melting point” means that at least about 80%, by weight, of the material corresponds to a single T_mpeak at a temperature within the range of from about 60° C. to 105° C., and essentially no substantial fraction of the material has a peak melting point in excess of about 115° C., as determined by DSC analysis. DSC measurements are made on a Perkin Elmer System 7 Thermal Analysis System. Melting information reported are second melting data, i.e., the sample is heated at a programmed rate of 10° C./min. to a temperature below its critical range. The sample is then reheated (2nd melting) at a programmed rate of 10° C./min. The presence of higher melting peaks is detrimental to film properties such as haze, and compromises the chances for meaningful reduction in the seal initiation temperature of the final film.

0030A homogeneous ethylene/alpha-olefin copolymer can, in general, be prepared by the copolymerization of ethylene and any one or more alpha-olefin. Preferably, the alpha-olefin is a C₃-C₂₀alpha-monoolefin, more preferably, a C₄-C₁₂alpha-monoolefin, still more preferably, a C₄-C₈alpha-monoolefin. Still more preferably, the alpha-olefin comprises at least one member selected from the group consisting of butene-1, hexene-1, and octene-1, i.e., 1-butene, 1-hexene, and 1-octene, respectively. Most preferably, the alpha-olefin comprises octene-1, and/or a blend of hexene-1 and butene-1.

0031Processes for preparing and using homogeneous polymers are disclosed in U.S. Pat. Nos. 5,206,075, 5,241,031, and PCT International Application WO 93/03093, each of which is hereby incorporated by reference thereto, in its entirety. Further details regarding the production and use of homogeneous ethylene/alpha-olefin copolymers are disclosed in PCT International Publication Number WO 90/03414, and PCT International Publication Number WO 93/03093, both of which designate Exxon Chemical Patents, Inc. as the Applicant, and both of which are hereby incorporated by reference thereto, in their respective entireties.

0032Still another genus of homogeneous ethylene/alpha-olefin copolymers is disclosed in U.S. Pat. No. 5,272,236, to LAI, et. al., and U.S. Pat. No. 5,278,272, to LAI, et. al., both of which are hereby incorporated by reference thereto, in their respective entireties.

0033As used herein, the term “polyolefin” refers to any polymerized olefin, which can be linear, branched, cyclic, aliphatic, aromatic, substituted, or unsubstituted. More specifically, included in the term polyolefin are homopolymers of olefin, copolymers of olefin, copolymers of an olefin and a non-olefinic comonomer copolymerizable with the olefin, such as vinyl monomers, modified polymers thereof, and the like. Specific examples include polyethylene homopolymer, polypropylene homopolymer, polybutene, ethylene/alpha-olefin copolymer, propylene/alpha-olefin copolymer, butene/alpha-olefin copolymer, ethylene/vinyl acetate copolymer, ethylene/ethyl acrylate copolymer, ethylene/butyl acrylate copolymer, ethylene/methyl acrylate copolymer, ethylene/acrylic acid copolymer, ethylene/methacrylic acid copolymer, modified polyolefin resin, ionomer resin, polymethylpentene, etc. Modified polyolefin resin is inclusive of modified polymer prepared by copolymerizing the homopolymer of the olefin or copolymer thereof with an unsaturated carboxylic acid, e.g., maleic acid, fumaric acid or the like, or a derivative thereof such as the anhydride, ester or metal salt or the like. It could also be obtained by incorporating into the olefin homopolymer or copolymer, an unsaturated carboxylic acid, e.g., maleic acid, fumaric acid or the like, or a derivative thereof such as the anhydride, ester or metal salt or the like.

0034As used herein, terms identifying polymers, such as “polyamide”, “polyester”, “polyurethane”, etc. are inclusive of not only polymers comprising repeating units derived from monomers known to polymerize to form a polymer of the named type, but are also inclusive of comonomers, derivatives, etc. which can copolymerize with monomers known to polymerize to produce the named polymer. For example, the term “polyamide” encompasses both polymers comprising repeating units derived from monomers, such as caprolactam, which polymerize to form a polyamide, as well as copolymers derived from the copolymerization of caprolactam with a comonomer which when polymerized alone does not result in the formation of a polyamide. Furthermore, terms identifying polymers are also inclusive of mixtures, blends, etc. of such polymers with other polymers of a different type. More preferably, however, the polyolefin is a the polymerization product of one or more unsubstituted olefins, the polyamide is the polymerization product of one or more unsubstituted amides, etc.

0035As used herein, the phrase “ethylene alpha-olefin copolymer”, and “ethylene/alpha-olefin copolymer”, refer to such heterogeneous materials as linear low density polyethylene (LLDPE), and very low and ultra-low density polyethylene (VLDPE and ULDPE); and homogeneous polymers such as metallocene-catalyzed EXACT® linear homogeneous ethylene/alpha olefin copolymer resins obtainable from the Exxon Chemical Company, of Baytown, Tex., and TAFMER® linear homogeneous ethylene/alpha-olefin copolymer resins obtainable from the Mitsui Petrochemical Corporation. All these materials generally include copolymers of ethylene with one or more comonomers selected from C₄to C₁₀alpha-olefin such as butene-1 (i.e., 1-butene), hexene-1, octene-1, etc. in which the molecules of the copolymers comprise long chains with relatively few side chain branches or cross-linked structures. This molecular structure is to be contrasted with conventional low or medium density polyethylenes which are more highly branched than their respective counterparts. The heterogeneous ethylene/alpha-olefin commonly known as LLDPE has a density usually in the range of from about 0.91 grams per cubic centimeter to about 0.94 grams per cubic centimeter. Other ethylene/alpha-olefin copolymers, such as the long chain branched homogeneous ethylene/alpha-olefin copolymers available from The Dow Chemical Company, known as AFFINITY® resins, are also included as another type of homogeneous ethylene/alpha-olefin copolymer useful in the present invention.

0036In general, the ethylene/alpha-olefin copolymer comprises a copolymer resulting from the copolymerization of from about 80 to 99 weight percent ethylene and from 1 to 20 weight percent alpha-olefin. Preferably, the ethylene/alpha-olefin copolymer comprises a copolymer resulting from the copolymerization of from about 85 to 95 weight percent ethylene and from 5 to 15 weight percent alpha-olefin.

0037As used herein, the phrase “cyclic olefin copolymer” is inclusive of all cyclic olefin polymers. Ethylene norbornene copolymer is a preferred cyclic olefin copolymer. In an embodiment, the ethylene/norbornene copolymer has a density of less than 0.98 g/cm³. In an embodiment, the ethylene/norbornene copolymer has a melt index of less than 1.5 dg/min.

0038As used herein, the phrases “inner layer” and “internal layer” and “intermediate layer” refer to any layer, of a multilayer film, having both of its principal surfaces directly adhered to another layer of the multilayer film.

0039As used herein, the phrase “outer layer” refers to any film layer of film having less than two of its principal surfaces directly adhered to another layer of the film. The phrase is inclusive of monolayer and multilayer films. In multilayer films, there are two outer layers, each of which has a principal surface adhered to only one other layer of the multilayer film. In monolayer films, there is only one layer, which, of course, is an outer layer in that neither of its two principal surfaces is adhered to another layer of the film.

0040As used herein, the phrase “inside layer” refers to the outer layer, of a multilayer film packaging a product, which is closest to the product, relative to the other layers of the multilayer film. “Inside layer” also is used with reference to the innermost layer (which is also an outer layer) of a plurality of concentrically arranged layers extruded through one or more annular dies. The inside layer is also frequently referred to as the “seal layer” or as the “heat seal layer.”

0041As used herein, the phrase “outside layer” refers to the outer layer, of a multilayer film packaging a product, which is furthest from the product relative to the other layers of the multilayer film. “Outside layer” also is used with reference to the outermost layer of a plurality of concentrically arranged layers extruded through one or more annular dies.

0042The packaging article can be used for the packaging of a wide variety of products, including both food products and non-food products. However, the film is especially useful as the top web in a vacuum skin package for the packaging of meat products, particularly bone-in meat products (pork chops, steaks, etc) and boneless meat products. Typical meat products include beef, pork, foul, fish, lamb, etc., and include fresh meat products and processed meat products, such as sausage. Higher implosion resistance is needed when vacuum skin packaging a plurality of bone-in pork chops, steaks, etc, in shingled configuration on the support member or in randomly placed configuration on the support member.

0043The top web film used in the packaged product can have a maximum thickness of from 3 to 9 mils, or from 3.2 to 8 mils, or from 3.4 mils to 7.5 mils, or from 3.6 mils to 7 mils, or from 3.8 mils to 6.5 mils, or from 4 mils to 6 mils. As used herein, the phrase “maximum thickness” is used because the top web is produced at a desired thickness but some portions of the top web are drawn down (i.e., reduced in thickness) by the thermoforming which occurs during the process of making a vacuum skin package. The portions of the top web which are not drawn down during the packaging process retain the maximum thickness of the top web, i.e., the original thickness of the top web before it is used in the vacuum skin packaging process.

0044In an embodiment, the top web film may have following layer arrangement:

0045(inside) Seal/1^stBulk/1^stTie/O₂-Barrier/2^ndTie/2^ndBulk/Abuse (outside)

0046In another embodiment, the top web film is made from a multilayer film of the following layer arrangement:

0000(inside) Seal/1^stBulk/2^ndBulk/1^stTie/O₂-Barrier/2^ndTie/2^ndBulk/Abuse (outside)

0047In an embodiment, the top web does not comprise ethylene/vinyl acetate copolymer.

0048In an alternative embodiment, the top web comprises ethylene/vinyl acetate copolymer in an amount of from 1 wt % to 10 wt %, based on total top web weight.

0049In an embodiment, the top web does not comprise ionomer resin.

0050In an alternative embodiment, top web comprises ionomer resin in an amount of from 1 wt % to 10 wt %, based on total top web weight.

0056The top web can comprise a first bulk layer between the first tie layer and the heat seal and product-contact layer, and a second bulk layer between the second tie layer and the outer abuse layer.

0057In an embodiment, each of the bulk layers comprises at least one member selected from the group consisting of ethylene/alpha-olefin copolymer and cyclic olefin copolymer.

0058In another embodiment, each of the bulk layers comprises at least one member selected from the group consisting of ethylene/alpha-olefin copolymer, cyclic olefin copolymer, ethylene homopolymer, ethylene/unsaturated ester copolymer, ionomer resin, propylene/ethylene copolymer, polystyrene, polyamide, polyester, and polycarbonate. Bulk layers are usually relatively thick, and/or are made from relatively strong polymers, as the purpose of bulk layers is to add strength, puncture resistance, etc. to the film.

0059If a blend of more than one ethylene/α-olefin copolymer is present, the blend is herein characterized as having an “average density” which is the weighted average of the densities of the various ethylene/α-olefin copolymers present, i.e., the densities of the various ethylene/α-olefin copolymers present taken in combination with their relative weight percent's in the blend. Similarly, the density of different ethylene/α-olefin copolymers in the heat seal and product-contact layer, together with the ethylene/α-olefin copolymers in the intermediate hulk layers, or any subset or set of layers, including up to all of the layers of the film, can be expressed as an “average density,” characterized with a weighted average of the densities of the group of polymers even if they are present in different layers, i.e., not all blended together.

0060The ethylene/α-olefin copolymers are primarily present in the heat-seal and product-contact layer and in the bulk layers. In an embodiment, the ethylene/α-olefin copolymer(s) in the top web have an average density of from 0.88 g/cm³to 0.915 g/cm³. In another embodiment, the ethylene/α-olefin copolymer(s) in the top web have an average density of from 0.885 g/cm³to 0.91 g/cm³. In another embodiment, the ethylene/α-olefin copolymer(s) in the top web have an average density of from 0.885 g/cm³to 0.91 g/cm³. In another embodiment, the ethylene/α-olefin copolymer in the top web has a density of from 0.90 g/cm³to 0.91 g/cm³. In another embodiment, the ethylene/α-olefin copolymer(s) in the top web have an average density of from 0.902 g/cm³to 0.908 g/cm³. In another embodiment, the ethylene/α-olefin copolymer(s) in the top web have an average density of from 0.90 g/cm³to 0.91 g/cm³.

0061In another embodiment, the ethylene/α-olefin copolymer comprises at least one heterogeneous ethylene/α-olefin copolymer(s) having an average density of from 0.90 g/cm³to 0.91 g/cm³. In another embodiment, the ethylene/α-olefin copolymer comprises at least one heterogeneous ethylene/α-olefin copolymer(s) having an average density of from 0.902 g/cm³to 0.908 g/cm³. In another embodiment, the ethylene/α-olefin copolymer comprises at least one heterogeneous ethylene/α-olefin copolymer(s) having an average density of from 0.904 g/cm³to 0.906 g/cm³.

0062In an embodiment, the top web film comprises ethylene/α-olefin copolymer having a melt index of from 0.5 to 4 dg/min, or 0.8 to 3 dg/min, or from 1 to 2 dg/min. In an embodiment, the top web film comprises ethylene/α-olefin copolymers having an average melt index of from 0.5 to 4 dg/min, or 0.8 to 3 dg/min, or from 1 to 2 dg/min. The average melt index is a weighted average of all the ethylene/alpha-olefin copolymer in the top web, determined in a manner corresponding with the manner in which average density is determined, as described herein. That is, the average density of more than one ethylene/alpha-olefin copolymer is a weighted average.

0063The multilayer top web film can comprise an oxygen barrier layer comprising a member selected from the group consisting of saponified ethylene/vinyl acetate copolymer, polyvinylidene chloride, and polyamide.

0064The multilayer top web film can comprise an outer abuse layer designed for the exterior of the final package. The abuse layer provides heat resistance during the vacuum skin packaging process.

0065The abuse layer may comprise at least one member selected from the group consisting of low density polyethylene, high density polyethylene, polypropylene, polyester (particularly polyethylene terephthalate), and cyclic olefin copolymer. For processability, melt indices of between about 5 and 8 are preferred for the abuse layer.

0066The top web can comprise a first tie layer between the oxygen barrier layer and the heat seal and product-contact layer, and a second tie layer between the oxygen barrier layer and the outer abuse layer. Preferred polymers for use in tie layers include ethylene/carboxylic acid copolymer, ethylene/ester copolymer, and anhydride-modified ethylene/alpha-olefin copolymer, anhydride-modified high density polyethylene, and anhydride modified low density polyethylene. Generally, tie layers are relatively thin, as their purpose is simply to provide a chemically compatible composition between two layers which otherwise do not bond with one another to a desired degree.

0067The film from which the top web is made may be partially or wholly irradiated to induce crosslinking. In the irradiation process, the film is subjected to an energetic radiation treatment, such as corona discharge, plasma, flame, ultraviolet, X-ray, gamma ray, beta ray, and high energy electron treatment, which induce cross-linking between molecules of the irradiated material. The irradiation of polymeric films is disclosed in U.S. Pat. No. 4,064,296, to BORNSTEIN, et. al., which is hereby incorporated in its entirety, by reference thereto. BORNSTEIN, et. al. discloses the use of ionizing radiation for crosslinking the polymer present in the film. The extrusion coating process illustrated in <figref idref="DRAWINGS">FIG. <b>2</b></figref> (described below) allows various layers to be extruded and crosslinked before an irradiation-sensitive polyvinylidene chloride O₂-barrier layer and other layers are extruded on top of the irradiated, crosslinked substrate portion of the multilayer film tubing, resulting in a stronger tubing film, whereas a full coextrusion of all the layers together, followed by irradiation, could result in degradation of the PVDC layer, causing a decrease in its oxygen barrier properties.

0068To produce crosslinking, a suitable radiation dosage of high energy electrons, preferably using an electron accelerator, with a dosage level being determined by standard dosimetry methods. Other accelerators such as a Van de Graaf generator or resonating transformer may be used. The radiation is not limited to electrons from an accelerator since any ionizing radiation may be used. The ionizing radiation can be used to crosslink the polymers in the film.

0069Although not illustrated in <figref idref="DRAWINGS">FIG. <b>2</b></figref>, preferably the film is irradiated at a level of from 180-220 kGy (kilograys). As can be seen from the descriptions of preferred films for use in the present invention, the most preferred amount of radiation is dependent upon the film composition, thickness, etc., and its end use.

0070In an embodiment, the support member is a multilayer structure comprising a support sheet having a liner film laminated thereto. In an embodiment, the support sheet is made from a member selected from the group consisting of polypropylene and polyethylene terephthalate.

0071In an embodiment, the liner film is a multilayer film having a bonding layer which is adhered to the support sheet, an outer heat seal &amp; food-contact layer, and an oxygen barrier layer between the heat seal &amp; food-contact layer and the bonding layer. The oxygen barrier layer may comprise a member selected from the group consisting of saponified ethylene/vinyl acetate copolymer, polyvinylidene chloride, and polyamide.

0072In the liner film, the heat seal &amp; food-contact layer may comprise any of the above-described polymers to be used in the heat seal and product-contact layer of the multilayer top web film.

0073In the liner film, the bonding layer may comprise anhydride grafted polypropylene.

0074In the liner film, the tie layer, which is between the oxygen barrier layer and the heat seal &amp; food-contact layer, may comprise at least one member selected from the group consisting of ethylene/carboxylic acid copolymer, ethylene/ester copolymer, anhydride-modified ethylene/alpha-olefin copolymer, anhydride-modified high density polyethylene, and anhydride modified low density polyethylene. This tie layer may be a first tie layer comprising an anhydride modified ethylene/α-olefin copolymer, with the liner film further comprising a second tie layer which is between the first tie layer and the heat seal &amp; food-contact layer. The second tie layer may comprise ethylene/methyl acrylate copolymer.

0075The liner film may have a maximum thickness of from 1.2 mils to 2 mils, or 1.4 mils to 1.8 mils.

0076In an embodiment, the support member is flat and comprises a flat support sheet and a flat liner film.

0077In an embodiment, the support member is a tray having a bottom product support portion and side walls extending upwardly from the product support portion, with the tray comprising a laminate comprising a support member having a liner film bonded thereto. An unformed laminate can be thermoformed to form the tray.

0078Various films were produced in the form of multilayer film tubings, using the process illustrated in <figref idref="DRAWINGS">FIG. <b>2</b></figref>. The process of <figref idref="DRAWINGS">FIG. <b>2</b></figref> is as generally disclosed in U.S. Pat. No. 4,287,151, to ESAKOV, et. al., hereby incorporated by reference thereto, in its entirety.

0079In the process illustrated in <figref idref="DRAWINGS">FIG. <b>2</b></figref>, tubular extrudate <b>260</b> was downwardly formed from die <b>262</b>, the tubular extrudate enclosing air mandrel <b>264</b>. At approximately this point in the process, an exterior cooling means, in the form of water ring <b>266</b>, encircles tubular extrudate <b>260</b>. Water ring <b>266</b> in the shape of a circular tray, had an opening therethrough, the opening having a diameter slightly larger than that of tubular extrudate <b>260</b>. A constant flow of water, at about 50° F., is supplied to water ring <b>266</b>. The overflow from the water ring provided an annular film of water on the outer surface of extrudate <b>260</b>. The water fell downwardly around the entire outer periphery of extrudate <b>260</b>, thereby cooling extrudate <b>260</b>. The film of water is collected by receptacle <b>268</b>. Water was the preferred cooling medium because its heat capacity and heat transfer characteristics are such as to cool extrudate <b>260</b> more rapidly than a chilled gas would have. However, as an alternative to water ring <b>266</b>, a fine spray of cooled water could have been directed against the exterior surface of the extrudate <b>260</b>. In combination, air mandrel <b>264</b> and water ring <b>266</b> serve as the means to cool and solidify extrudate <b>260</b>. In some instances, depending upon the polymer being extruded and upon the wall thickness of extrudate <b>260</b>, either the interior or exterior cooling could be eliminated, because one cooling means alone would be sufficient to solidify the interior tube wall before reaching support plug <b>270</b>. Once solidified, extrudate <b>272</b> is collapsed by rolls <b>274</b>, to form a solidified lay flat tubing <b>276</b>. The wound up film can be irradiated before windup or unwound and irradiated before use.

0080<figref idref="DRAWINGS">FIG. <b>4</b></figref> illustrates packaged product <b>80</b> comprising a plurality of pork chops <b>82</b> having bones <b>84</b> are more or less randomly arranged on a thermoformed tray <b>86</b> which is a support member made from a polypropylene sheet to which a liner film has been bonded, with the resulting laminate being thermoformed into tray <b>86</b>. The transparent top web has been heated and draped over tray <b>86</b> and product <b>82</b>, so that product <b>82</b> is vacuum packaged and surrounded by the combination of the transparent top web and the liner film bonded to the support member. As both the liner film and the top web are multilayer films comprising an oxygen barrier layer, the shelf life of product <b>82</b> is extended by vacuum skin package article. The convoluted top surface produced by the random arrangement of the bone-in pork chops <b>82</b> produces a plurality of cavities <b>88</b> into which the top web is thermoformed during the vacuum skin packaging process. Unless the top web is capable of withstanding the stress of the heavy degree of thermoforming into cavities <b>88</b>, the top web will break, causing the package to fail. However, the top web utilized in the package of <figref idref="DRAWINGS">FIG. <b>4</b></figref> exhibited a high degree of Implosion Resistance, as it is in accord with the first aspect, described above.

Implosion Resistance Test

0081The Implosion Resistance Test is illustrated in <figref idref="DRAWINGS">FIG. <b>3</b></figref>. The Implosion Resistance Test measures the maximum diameter of the openings over which the top web can be heated and stretched, without breaking, during vacuum skin packaging.

0082A drilled wooden block <b>30</b> is drilled part way through with a series of bits of different diameters, ranging from the smallest diameter of 5/16 (8 mm) inch, to the largest diameter of 1 inch (25.4 mm). In block <b>30</b> as illustrated in <figref idref="DRAWINGS">FIG. <b>3</b></figref>, bores <b>32</b>, <b>34</b>, <b>36</b>, <b>38</b>, and <b>42</b> extend into the block from respective openings. Each bore has been drilled to the same depth of one inch. The openings are circular holes defined by the intersection of each cylindrical bore with the planar upper face of wooden block <b>30</b>.

0083The block is vacuum skin packaged in a CRYOVAC RTM VS-44 machine. The top web film <b>44</b> is used to completely envelop the block <b>80</b>. During the packaging tests with wooden block <b>30</b>, the film tends to undergo a stretching stress which increases with the increasing hole diameter. In the example illustrated in <figref idref="DRAWINGS">FIG. <b>3</b></figref>, film portions <b>46</b>, <b>48</b>, <b>50</b>, <b>52</b>, and <b>54</b> stretch without breaking over the holes <b>32</b>, <b>34</b>, <b>36</b>, <b>38</b>, and <b>40</b>, but film portion <b>56</b> breaks inside hole <b>42</b>. The diameter in mm of the largest hole before the film becomes broken (i.e., hole <b>40</b> in the test illustrated in <figref idref="DRAWINGS">FIG. <b>2</b></figref>) is the implosion resistance rating of the top web film being tested. The implosion resistance rating is highly representative of the film packaging ability of the top web film in a vacuum skin packaging process. A set of 44 tests are performed on each film, with the results averaged, to provide an “average implosion resistance”. The test is conducted in a room at 23 C and 1 atm pressure and 50% relative humidity.

0084The packaging tests on block <b>30</b> were conducted throughout the examples herein on a CRYOVAC VS44 machine equipped with a rotary vacuum pump and a serially connected auxiliary pump. The temperature under the heater bell was of 200° C., and the films were infrared pre-heated up to 70° C. to 80° C. The level of the vacuum provided varied between 3 and 6 millibars.

0085The top web film can have an average implosion resistance of at least 11.5 millimeters, or at least 13 millimeters, or at least 14 millimeters, or at least 14.5 millimeters, or at least 15 millimeters, or at least 15.4 millimeters, or at least 15.8 millimeters, or at least 16 millimeters.

0128In Table 35, above, the amount of ethylene/α-olefin copolymer is calculated based on ethylene/α-olefin copolymer in the seal layer and the bulk layers, but does not include the small qualities of ethylene/alpha-olefin copolymer in the slip agents used in the outer layers of the top web film. Although the small quantities of ethylene/α-olefin in SLIP1 and SLIP3 may have contributed to implosion resistance and slightly elevate the weight percent ethylene/alpha-olefin copolymer reported for the films, all of the films contained about the same amounts of these slip agents so the small effect did not alter the relative implosion resistance results for the films, i.e., the implosion resistance relative to each other.

0129As is apparent from the data above, the top webs containing a styrene-butadiene-styrene block copolymer (Film No. 11) or a blend of propylene/ethylene copolymer (PEC) and styrene butadiene styrene copolymer (Film Nos. 8-10) also exhibited poor results in the Implosion Resistance Test (average of 0 mm). The three top webs containing ethylene/vinyl acetate copolymer (Film Nos. 1, 2, and 16) exhibited mediocre implosion resistance in a room temperature Implosion Resistance Test (average of 8.6 mm). Similarly, the only top web containing ionomer resin (Film No. 7) also exhibited mediocre poor implosion resistance in the room temperature Implosion Resistance Test (11.4 mm).

0130In contrast, top web Film Nos. 21-29, which containing a blend of ethylene/alpha-olefin copolymer and cyclic olefin copolymer (i.e., COC, which was solely ethylene norbornene copolymer, ENB) exhibited good implosion resistance in the Implosion Resistance Test, i.e., an average Implosion Resistance of (average value 13.7 mm). Those with predominantly ENB1 (i.e., Film Nos. 23, 24, 25, 27, avg implosion resistance 12.2 mm), which had a density of 1.02 and a melt index of 2.04 dg/min, did not perform as well as those with predominantly ENB2 (Film Nos. 18, 19, 20, 21, 22, 26, average implosion resistance 14.7 mm), which had a density of 0.974 and a melt index of 1.0 dg/min.

0131Moreover, Film Nos. 18 and 19, which contained 25 wt % to 40 wt % COC in the seal layer in a blend with ethylene/α-olefin copolymer, exhibited some of the highest average implosion resistance values (16.3 mm and 16.2 mm, respectively).

0132The top webs containing ethylene/α-olefin copolymer without cyclic olefin copolymer (i.e., Film Nos. 3-6, 12, 13, 14, 15, 17-20, 31) exhibited an average implosion resistance value of 13.8 mm in the Implosion Resistance Test conducted at room temperature.

0133The best implosion resistance was obtained from the top webs containing a relatively high fraction of relatively low density heterogeneous ethylene/α-olefin copolymer in the seal and bulk layers, either with or without a COC present in the seal layer or bulk layer, so that either the ethylene/α-olefin copolymer alone or the ethylene/α-olefin plus the COC together made up at the majority of the weight of the top web film, i.e., Film Nos. 5, 6, 17, 18, 19, 21, 22, 25, 26, 27, 28, 29, and 31. These top web films exhibited an average room temperature Implosion Resistance Test Result of 14.5 mm. The films containing a low density heterogeneous ethylene/α-olefin copolymer (0.9025 g/cm³) in the bulk layer and from 25 wt % to 40 wt % COC in the seal layer.
